Coal beneficiation is achieved by suspending coal fines in a colloidal suspension of microscopic gas bubbles in water under atmospheric conditions to form small agglomerates of the fines adhered by the gas bubbles. The agglomerates are separated, recovered and resuspended in water. Thereafter, the pressure on the suspension is increased above atmospheric to …

As the name implies, the grinding media in these mills are steel balls. The particles size of the feed usually does not exceed 2.5 cm. The grinding is carried out by balls being carried up the side of the mill such that they release and fall to the point where they impact the ore particles in trailing bottom region of the slurry.

Prior to 1950, there were no Beneficiation plants, since selective mining was in practice. 9 The first Indian coal washery was set up at West Bokaro in 1951, followed by the second one installed at Jamadoba in 1952 – both by M/s Tata Iron and Steel Limited. The third washery came up at Lodna colliery by M/s Turner Morrison in 1955.
